We propose a numerical test of the non-parametric conditions for additive separability between consumption and real money balances, building on Varian (1983). If additive separability is rejected, then real balances enter into the theoretical IS curve. We test whether or not monetary assets and...

This paper uses several methods to study the interrelationship among Divisia monetary aggregates, prices, and income; allowing for non-stationary, non-linearities, asymmetries, and time-varying relationships among the series. We propose a multivariate regime switching unobserved components model...
